To all whom it may concern.'

Beit known that l, RAPHAEL H. GELINAS, a citizen of the United States, residing at South Hadley Falls, in the county of Hampshire and State of Massachusetts, have invented an Improvement in Harness Stop-4 Motions for Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like arts. p The invention to be hereinafter described relates to looms, and more particularly to the harness stop motions employed therein for stopping the loom when one of the harnesses 'drops or falls during the weavingoperation.

Should one of the harness supporting or operating means break or become disconnected from a harness while the loom is runf ning great injury to the warp threads controlled by that harness and other parts is liable to occur unless the loom is promptly stopped, and various forms of means have been devised for this purpose. On the other hand should the loom be prematurely started or set in operation before complete repairs have been eected and the parts properly adjusted, warp threads are liable to be broken, imperfect cloth'woven, and other objectionableresults occur.

@ne of the important features of the present invention therefore consists in a harness stop motion of simple and novel construction which will insure prompt stoppage of the loom when one or more of the' harnesses drops orfalls from any cause, such, for instance, as a broken harness support or operating means.

Another important feature of the Vinvention consists in a lock rendered eiiective when the loom is stopped by a dropped or fallen harness to prevent starting the loom again until the loom fixer or attendantlirst manipulates the lock to release the loom from its control.

Other important features of the invention consist inthe novel combination of parts, which in addition to the above will be herein fully described and then deinitely pointed out in the claims.

ln the drawings:

Figure 1 is a side elevation and part sectional view with parts broken away showing a loom provided with the present invention;

Fig. 2 is a perspective view showing more particularly the harness stopmotion devices, the loom frame and other parts being broken 'away or omitted for clearness of illustraframes are the standards or arches 4 for sus taining the harness supports as usual. In the present instance of the invention the standards or arches 4 have the cross member 5 which supports the rockers 6v about which the supports or suspending means 7 connected to the harness frames 8 pass, the construction being 'such that the harnesses, of which there may be any suitable number, v.

may be suspended from the rocker or rockers 6 of appropriate number by the suspending or supporting straps 7 substantially as indicated in Fig.4 1.

The lower bars of the harnesses have connected thereto lthe operating connections 9 with the cam actuatedV levers l0 by which the harnesses are reciprocated as usual in the weaving operation.

Mounted forreciprocating movement toward and from the front of theloom is the` lay 11 supported by the lay swords 12, which, as usual are supported for rocking movement at the lower part of the loom frame. The shipper handle 13, as usual, may control the operative and inoperative condition of the loom, the construction being such that when theI shipper handle 13 is held in the locking notch of the shipper stand the loom will be in operation and when the shipper is detached from the holding notch it will, under the actuation of spring means, as usual, effect loom stoppage. The construction and operation of the parts thus far described are well understood by those skilled in the art and further elucidation is unnecessary. l

A shaft 14 is suitably supported for rocking movement -and'is provided tvith one, two

or more arms 15 which extend under the series of harnesses as indicated in Figs. 1

and 2, the `cmstruction being such that shouldA anyone of the harnesses drop or fall by reason of breakage of parts, as for instance its support or suspending strap 7 as indlcated in- Fig. 1, such harness will engage one ofthe arms 15 and cause the shaft 14 to be moved or rocked. 1n the present instance of the invention, the shaft 14 is supported in slotted bearings 16 by means of shaft 14 in one direction, or clockwise in the present instance. In order that the rock shaft 14 may be sensitive and have its sensibility adjusted to suit conditions of use from time to time, a countervveight 19 is employed to act in op ositionto the spring 18. The counterweig t 19- is or maybe preferably adjustably mounted on an arm 20 secured to the shaft 14,- as indicated inv Fig. 2.

The slotted bearings 16 may be sustained lby appropriate means but in the present instance are formed `upon the fixed arms 21 sustained upon uprights 22 which may be appropriately secured to the floor or ma-A chine frame as circumstances may dictate.

When a harness drops by reason of breakage in its supporting or suspending strap and turns the shaft 14, it is desirable that the loom be promptly brought to rest, other- Wise great injury is liable to result to the Warp threads and other parts. Various means may suggest themselveslas appropriate to effect loom stoppage when the shaft 14 is rocked and in the present instance of the invention a finger or stop device is so connected with the shaft 14 that upon rockharness, the stop device Will be moved in the path of a vibrating feeler and arrest su'ch feeler to thereby stop the loom. Secured to the shaft 14 is an arm 23, Fig. 2, the free end of which at 24 engages an arm 25 connected to the stop 26 pivotally supported at 27, the construction being such that upon rocking movement being imparted to the shaft 14, ythe stop 26 will be moved into the path of a vibrating feeler.

'I lhe vibrating feeler may be variously contrived but in the present instance of the invention advantage is taken of the warp stop motion feeler. Looms are usually provided with warp sto'p motions and in the present instance of the invention the warp-threads are shown as sustaining the detectors or drop devices 28 which upon breakage of a thread will drop into the path of a vibratingv feeler 29 and arrest its motion.

The stop 26 is therefresoldisposed with relation to the vibrating feeler 29 that when the rockshaft 14 is turned by a drop harness the `finger l26 ,will arrest vibrating movement of the feeler 29.

. .The feeler 29 is supported upon a. rock shaft 30 having a crank. arm 3l to which is connected one end of a link 32, the lower end thereof being pivotally connected at 33 to a lever 34 pivotally mounted at 35 and having its `end 36 bearing ufpon the periphery of a cam 37 mounted upon the under or cam shaft 38. In order to hold the end 36 of the lever against its actuating cam 37' a suitable spring may beemployed which, in the present instance of the invention, is indicated at 39, Figs. 1 and 2, one end of the spring being secured to the outer end of the lever *34 and the other end to. a ixed bracket 40.

Secured to the rock shaft 30 onwhichA the feeler is mounted and disposed near one ciprocating the bunter 48 will be appro-- priately moved. 'The bunter 48 is carried by an arm 49 pivotallyumounted at 50 on the loom frame, the construction being such that the bunter may be moved bodily relative to ,the short rock shaft 44 and the bunter controller. Connected to the arm 49 is a link 51 the forward end of which is connected at 52, Fig. 2, with 'a knock-off 53 pivoted at 54 and having an end portion 55 which, when the shipper handle 13 .is in its holding* notch as usual during loom operation, rests in front of the shipper,'the construction being suchthat should the bunter 48 be moved 'rearwardly the knock-oE53 will be actuated `to detach the shipper from its holding notch and effect loom stoppage either by shipping a belt or disengaging the clutch members as will be readily understood .by those skilled in the art.

Mounted for movement With-the lay is a part 56, Figrl, which, when the bunter 48 fails to be moved by the vibrating feeler, is adapted to engage the bunter on the backward movement of the la;r and through the means described effect loom stoppage. Thus, when one of the harnesses drops or falls, due to breakage in one of the harness supports or lfrom any other cause, the rock shaft 14 will be turned and through the described train of mechanism the loom will be promptly brought torest.

Vside ofthe loom frame, is an arm 41, Fig.

therefore, contemplates the provision of means for automatically locking the loom when it has been stopped by afallen or `dropped harness and to maintain the loom in such locked condition that it may not be started again until the loom iixer or attendant has manually manipulated theloek comprises inte tion when the locking arm is moved by the.

Ysans; 14, win be bmg 4mm2() is extended rearw to release the loom from its control, whereupon the shipper may be moved as usual and the loom be The lock may be variously contrlved, but in the present insta' nce of the ieiventici 1111;,

rengagm mem rs w c when `the rock shaft 14 ligas been rocked by a dropped or fallen harness, and the linger 26 moved into the npath of the vibrating feeler, will maintain the parts in such assumed'position and consequently prevent starting the loom until the parts are released from the control of the lock. In the present instance the lock consists, in part, of the arm 20 heretofore referred to, which is extended rearwardly and appropriately formed-at its rear portion to constitute a locking arm which, when moved by movement of the 'intlo locking l gement with a coperang ockmg` ca ferring more particularl to Fig. 2 the y as at? and appropriately turned at 58 to present a locking member 59. The pprtion 59 may be appropriately bent laterally and then turned upwardly at 6 0to embrace the stationary arm 20 and serve as a guide for guiding the movement of the arm 20 as the shaft 14 is rocked. Pivotally mounted upon one of the uprights or supports 22 at 61 is the locking catch which comprises an arm 62 having an abruptly bent portion 63 and a curved locking portion 64 which may be extended to form an operating lever 65 for. disengaging the parts of the lock when the loom fixer or attendant has completed the desired repairs. The arm 65 may appropriately be provided with a small weight 66 which will serve to depress the locking catch into locking posirock shaft 14 as indicated in Fig. 1.

When the parts are in unlocked relation and the loom is running the elbow or abruptly bent portion 63 of the locking catch 63 rests upon the bent portion 59 of the locking arm as indicated 'in Figs. 2 and 3. In order to more eil'ectually maintain the parts in this relation the elbow or abruptly bent portion 63 of the locking catch may be provided with a recess 67 appropriately formed to engage the portion 59 of the locking arm. The parts being in the position as indicated in Fig. 2 and the loom normally running,

weight 66, turn from the falling of a harness to prevent starting should one of the harnesses drop apd the rock-shaft 14 be thereby turned, the locking arm 57 will move downwardly and the locking catch 62 will, by reason of the position indicated in Fig. 2 to that of Fig. 1, thereby locking the arm 57 in its lowered position and perforce the stop 26 in that the loom is locked Aand prevented from being started again' until the locking device is manipulated to free the loom from its control.
